Memory is malleable, dynamic and elusive. In this hour, TED speakers discuss how a nimble memory can improve your life, and how a frail one might ruin someone else's.

Joshua Foer, "..our lives are the sum of our memories. How much are we willing to lose by not paying attention to the human being across from us who is talking with us, by being so lazy that we're not willing to process deeply?...if you want to live a memorable life, you have to be the kind of person who remembers to remember."
